Performance Verification

Performance Verification Procedures

Two types of Performance Verification procedures can be performed on this
product; Brief Procedures and Performance Tests. You may not need to perform
all of these procedures, depending on what you want to accomplish.

H To rapidly confirm that the analyzer functions properly and was adjusted

properly, do the brief procedures under Functional Tests and Diagnostics,
which begin on page 1–3.

Advantages: These procedures are quick to do, require no external
equipment or signal sources, and perform functional and accuracy testing to
provide high confidence that the analyzer will perform properly. They can be
used as a quick check before making a series of important measurements.

H If more extensive confirmation of performance is desired, do the Perfor-

mance Tests, beginning on page 1–9, after doing the Functional Tests and
Diagnostics just referenced.

Advantages: These procedures add direct checking of warranted specifica­tions.

Disadvantages: They require more time to perform and suitable test
equipment is required. (Refer to Equipment Required on page 1–11.)

Conventions

Throughout these procedures, the following conventions apply:

H Each test procedure uses the following general format:

Title of Test

Equipment Required

Prerequisites

Procedure

H Each procedure consists of as many steps, substeps, and subparts as required

to do the test. Steps, substeps, and subparts are sequenced as follows:

1. First Step

a. First Substep

H First Subpart

H Second Subpart

b. Second Substep

2. Second Step

H Instructions for menu selection follow this format:

FRONT PANEL KEY Õ Side Menu Key Õ Submenu Key.
For example, “Press MODE: DEMOD Õ Digital Demod Õ Constellation”.
“MODE: DEMOD” indicates the DEMOD key in the MODE menu area on
the front panel.

H In steps and substeps, the lead-in statement in italics tells you what to do,

and the instructions that follow tell you how to do it.
The example step below is telling you to set the analyzer controls by
pressing the specified key sequence.

Set the RSA3408A analyzer controls:
Press MODE: DEMOD Õ Digital Demod Õ Constellation.

STOP. The symbol at the left is accompanied by information you must read to do
the procedure properly.

Brief Procedures

The Functional Tests use the internal calibration signal as a test-signal source for
further verifying that the analyzer functions properly.

The Diagnostics use internal routines to verify that the instrument functions
properly and passes the internal circuit tests.

The following section provides the details.

Performance Tests

This section contains procedures for checking that the RSA3408A 8 GHz
Real-Time Spectrum Analyzer performs as warranted.

The procedures are arranged in four logical groupings:

H Frequency Checks

H Noise Sideband Checks

H Amplitude Checks

H Spurious Response Checks

They check all the characteristics that are designated as checked in Chapter 2,
Specification. (The characteristics that are checked appear with the n symbol in
the Characteristics column in Chapter 2.) You can use the form at the end of this
section as a test record.

Read Performance Verification Procedures that start on page 1-1. Also, if you
are not familiar with operating this analyzer, read the RSA3408A User Manual
before doing any of these procedures.

STOP. These procedures extend the confidence level provided by the basic
procedures described on page 1–3. Perform the basic procedures first and then
perform the following procedures if desired.

RSA3408A Technical Reference

Performance Tests

Prerequisites

The tests in this section make up an extensive, valid confirmation of performance
and functionality when the following requirements are met:

H The cabinet must be installed on the analyzer.

H The instrument must have passed the procedures under Brief Procedures

found on page 1–3.

H A signal-path compensation must have been done within the recommended

calibration interval and at a temperature within ±3 _C of the present
operating temperature. (If at the time you did the prerequisite Brief Proce-
dures, the temperature was within the limits just stated, consider this
prerequisite met.)

H The analyzer must have been last adjusted at an ambient temperature

between +20 _C and +30 _C, must have been operating for a warm-up
period of at least 20 minutes, and must be operating at an ambient tempera­ture of between +10 _C and +40 _C. (The warm-up requirement is usually
met in the course of meeting the Brief Procedures prerequisites listed above.)

2. Check frequency accuracy in the baseband:

a. Modify the analyzer default settings:

H Press the FREQUENCY/CHANNEL key on the front panel.

H With the Center Freq side key, set the frequency to 10 MHz using

the numeric keypad.

H Press the SPAN key on the front panel.

H With the Span side key, set the span to 1 MHz using the general

purpose knob.

b. Measure peak frequency:

H Press the PEAK key to place the marker on the peak signal.

H Read the marker readout. Confirm that the value is

10 MHz "1 kHz.
